7 Obtaining the ESNThe Electronic Serial Number (ESN) is a unique identifier of a Network Element (NE). Recordthe ESN for later commissioning of the base station before installation.

ProcedureStep 1 Record the ESN on the BBU.

l If there is not a label on the FAN unit of the BBU, you must record the ESN and siteinformation that is printed on a mounting ear of the BBU. Figure 7-1 shows the position ofthe ESN.

l If there is a label on the FAN unit of the BBU, the ESN is printed on the label and a mountingear of the BBU. In this case, you must take the label and record the site information on theside labeled Site, as shown in Figure 7-2.

11-1

11.1 Cabling RequirementsRoute cables according to the specified cabling requirements to prevent signal interference.

NOTEIf a cable listed below is not required, skip the routing of the cable.

General Cabling RequirementsThe bending radius of the cables must meet the following specifications:l The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending

radius of the 5/4'' feeder must be more than 380 mm (14.96 in.).l The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending

radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bendingradius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.).

l The bending radius of the power cable or PGND cable must be at least five times thediameter of the cable.

l The bending radius of the optical fiber must be at least 20 times the diameter of the opticalfiber.

l The bending radius of the E1/T1 cable must be at least five times the diameter of the cable.l The bending radius of the signal cable must be at least five times the diameter of the cable.The cables must be bound as follows:l Different types of cables must be separately routed and cannot be entangled.l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.l The cable ties must face the same direction, and those at the same horizontal line must be

in a straight line. Extra length of cable ties must be cut.l Labels or nameplates must be attached to the cables after they are installed.The cables must be routed as follows:l Different types of cables must be separately routed with a minimum space of 30 mm (1.18

in.) between every two cables.l Different types of cables must be installed in an untangled and orderly fashion.l Different types of cables must be routed in parallel or separated by special objects.

Special Cabling RequirementsCabling requirements for power cables are as follows:l -48 V power cables must be bound together.l +24 V power cables must be bound together.l Power cables, transmission cables, and signal cables are routed separately.l Multiple power cables must be bound when routed.l Power cables must be installed in the position specified in engineering design documents.l If the length of power cables is insufficient, replace the cables rather than adding connectors

or soldering joints to lengthen the cables.

11 Installing IMB03 CablesDBS3900 WiMAX



Issue 03 (2011-01-25)

Cabling requirements for PGND cables are as follows:l PGND cables for the base station must be connected to the same ground bar.l PGND cables must be buried in the ground or routed indoors. They should not be routed

overhead before they are led into the equipment room.l The exterior of the coaxial wire and the shield layer of the shielded cable must have proper

electrical contact with the metal surface of the equipment to which they are connected.l PGND cables and signal cables must be installed in an untangled and orderly fashion. A

certain distance must be reserved between them to prevent interference from each other.l Fuses or switches must not be installed on the PGND cables.l Other devices must not be used for electrical connections of the PGND cables.l All the metal parts in the housing of the equipment must be reliably connected to the ground

terminal.Cabling requirements for E1 cables are as follows:l E1 cables must not cross power cables, PGND cables, or RF cables when routed. If

transmission cables are routed with power cables, PGND cables, or RF cables in parallel,the spacing between them must be greater than 30 mm (1.18 in.).

l E1 cables are routed straightly and bound neatly with cable ties.l Sufficient slack is provided in E1 cables at turns.Cabling requirements for optical fibers are as follows:l Do not stretch, step on, or place heavy objects on optical fibers. Keep the fibers away from

sharp objects.l When optical fibers are routed, the extra length of the fibers must be coiled around special

devices, such as a fiber coiler.l When coiling optical fibers, apply even strength. Do not bend the fibers with force.l Vacant optical connectors must be covered with dustproof caps.

11.2 Cable Installation ProcessThis section describes the process of installing IMB03 cables.

Process of Installing IMB03 CablesFigure 11-1 shows the cable installation process.
